WEAP Future Scenarios Model for Water Plan Update 2023

Listed in California Open Data

California Water Code Section 10004.6 requires the California Department of Water Resources (DWR) to quantify current and future water conditions in the state.

Description

This information is published in the California Water Plan (Water Plan), which is updated every five years. Water Plan Updates 2005, 2009, 2013, 2018 and 2023 have progressively developed a Water Evaluation And Planning (WEAP) model for assessing the impacts of climate change on California water resources and infrastructure, as well as the adaptation strategies needed and available to improve regional water resilience.

Update 2023 brought significant improvements to input data and process in the model as described in the model documentation provided in the resources. The current WEAP model is called the WEAP-CVPA model as it covers the Central Valley of California at the planning area scale. The model was run on WEAP version 2021.0.2.2 but is compatible with newer versions of WEAP based on limited testing.

Included in this dataset is:

  • The model itself with input files provided as a zip file
  • A link to SEI’s website where the software to run and view the model can be downloaded
  • The documentation for the model that was released as part of the California Water Plan Update 2023
  • 4 CSVs with the post processed data from the study that were used to create the Future Scenarios Interactive Data Explorer, separated by summary vs detailed response surface as well as by planning area metrics vs points of interest metrics
  • A link to the Future Scenarios Interactive Data Explorer where the post processed results and response surfaces available at the planning area level
  • The raw exports from the model of the level 2070 that were post processed to create the data that informed the Water Plan Update 2023
  • Spatial Boundaries for Water Plan Planning Areas which were used as the basis for spatial areas in the WEAP model
